ELECTRIC TROLLEY.

SPECIFICATION forming part of Letters Patent No. 766,650, dated. August 2, 1904,

Application filed March 10, 1904.

To all whom it may concern.-

Be it known that I, GEORGE Oxno, a citizen of the United States, and a resident of Delancey, in the county of Jefferson and State of Pennsylvania, have invented a new and Im proved Electric Trolley, of which the following is a full, clear, and exact description.

This invention relates to electric trolleys; and it consists, substantially, in the construction and combinations of parts hereinafter particularly described, and pointed out in the claims.

The invention has reference more especially to what are technically known as trolley-finders, and one of the principal objects thereof is to overcome numerous disadvantages and objections common to many other structures hitherto devised for a similar purpose and also to provide a device of this kind which is simple in construction and comparatively inexpensive to manufacture.

A further object is to provide a device of the character referred to which is not liable to get out of order or become broken and which is strong and durable and readily manipulated, besides possessing the capacity for long and repeated service.

The above and additional objects are attained by means substantially such as are illustrated in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views.

Figure l is a view in perspective, showing an electric-trolley device having my improvements embodied in connection therewith; and Fig. 2 is a longitudinal sectional elevation showing the construction and organization of parts more clearly.

Before proceeding with a more detailed description it may be stated that in the embodiment of my improvements herein shown I employ an ordinary form of trolley-head in which is rotatably mounted the usual wheel for traversing the overhead conductor or feed-wire, and supported by the structure above the head is a specially-constructed yoke the side members of which extend along and beyond the sides of the wheel at or near its edges, the free extremities of said members being pro- Serial No. 197,398. (No modal.)

vided with specially constructed shoes, between which is effected the ready placing of the wheel in contact with the conductor, said shoes also operating to permit the entire structure to pass the usual overhead supports for the conductor, and the said free extremities of the yoke members having thereon special devices for preventing separation of the structure from the conductor in use or operation. Special operating devices are also employed for throwing the side members of the yoke outwardly with respect to each other, so as to separate the shoes either for the purpose of applying the wheel or disconnecting the structure from the conductor, and while I have herein represented my improvements in a certain selected embodiment it will be understood, of course, that :I am not limited to the precise details thereof in practice, since immaterial changes therein may be restored to coming within the scope of my invention.

Specific reference being had to the drawings by the designating characters marked thereon, 1 represents the upper end portion of an ordinary trolley-pole 2, the same being preferably reduced and threaded at 3 and having applied or titted thereto an ordinary trolleyhead 4, between the ends of the parallel cheekpieces 5 of which is mounted the spindle 6 of an ordinary grooved trolley-wheel 7, designed to travel in electrical contact with an overhead conductor or wire 8. Clampcd either to said reduced end portion of the pole or the part of the head 3 adjacent thereto is a yoke 8, notched at the sides thereof at 9 to receive the inner extremities 10 of substantially duplicate side members 11, working in slots 12 in a guide 13 therefor, mounted across the upper edges of said cheek-pieces of the head, the said side members extending along and beyond the sides of the wheel, as shown, and provided at the outer or free extremities thereof with opposite inturned branches 14.

The inner extremity of each of the side members 11 of the yoke is formed with a slot 15, through which extends a lug 16 from the yoke, having therein an opening in which is inserted a locking-pin 17 for sustaining the member in movable relation to the yoke, it being noted that the said members of the yoke are connected by preferably two springs 18 and 19, located between the same at either side of the said guide 13, said springs normally maintaining the members in parallelism and tending to force or press the opposite inner faces of the branches 14 thereof close together. I

Loosely connected to the members of the yoke at 20 are the corresponding ends of two links 21, which cross each other, as shown at 22, and have their other ends in movable connection with eyes 23, rigid with the upper surface of one arm, 24, of a lever pivoted at 25, preferably at the crotch of the cheekpieces 5 of the trolley-head, and having connected to the end of the other arm, 26, thereof an ordinary pull rod or chain 27 By pulling downwardly on the said lever-arm 26 the arm 24 thereof will of course be thrown upwardly, thereby moving the links and spreading them apart in such manner as to force or carry the side members of the yoke outwardly, or away from each other, as is apparent, such outward movement of said members being limited, however, by the outer edges of the slots 12 of the guide 13, in which they work, and on releasing downward strain from the lever-arm 26 the springs 18 and 19 immediately restore said side members to their original or normal positions.

The outer extremity of each side member of the yoke is provided with a shoe comprising in the present instance a flat spring 28, applied to the inner face of the branch 14 of the member in any suitable way and extending beyond said branch in either direction longitudinally of the conductor 8, another spring, 29, being applied to the outer face of the branch at 30 and tending at its ends to press inwardly against the ends of its companion spring 28. The ends of said springs 28 are curved or turned outwardly from each other, as indicated at 31 and 32, so that throats 33 are thus formed to facilitate the entrance between the shoes of the usual supports 34 for the overhead conductor in the passing of said supports by the trolley device'in either direction. The upper surface of each of the branches 14 of the side members of the yoke is provided with a rotatable disk 35, a portion of which continually overlaps the other branch in such manner as to prevent the trolley device leaving the conductor even on slight separation of the said side members and the tor and retained in such relation and also how the same may be separated entirely from the conductor when desired.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent 1.
